Question

Match the following types of nuclei with examples shown: 

• A. A - iii, B - ii, C - i
• B. A - ii, B - iii, C - i
• C. A - ii, B - i, C - iii
• D. A - i, B - iii, C - ii

Hint:

Isotopes have the same atomic number, isobars have the same mass number, and isotones have the same number of neutrons.

Answer 1

The Correct Option is C

Isotopes are atoms of the same element with different numbers of neutrons. They have the same atomic number but different mass numbers. For example, \( ^{14}C \) and \( ^{12}C \) are isotopes of carbon, so \( A \) corresponds to (ii). Isobars are atoms of different elements that have the same mass number but different atomic numbers. For example, \( ^{16}O \) and \( ^{18}O \) are isobars, so \( B \) corresponds to (i). Isotones are atoms that have the same number of neutrons but different numbers of protons. For example, \( ^{14}N \) and \( ^{15}N \) are isotones, so \( C \) corresponds to (iii). Thus, the correct matching is option (3): A - ii, B - i, C - iii.
